END-GATE AND LIFTINGJACK.

Specification of Letters Patent.

Patented Jan. 31, 1911.

Application filed March 17, 1910. Serial No. 549,998.

To all whom it may concern:

Be it known that I, ORSON B'UCKLIN, a citizen of the United States, residing at Marietta, in the county of Lac qui Parlc and State of Minnesota, have invented a new and useful End-Gate and Lifting-Jack, of which the following is a specification.

This invention relates to a combined end gate and lifting jack.

The objects of the invention are to improve and simplify the construction of end gates and lifting jacks disclosed in my United States Patent No. 831,534, dated September 25, 1906.

l/Vith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the eombination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood thatchanges in the precise embodiment of invention herein disclosed can be made within the scope of the claims without departing from the spirit of the invention.

In the acompanying drawing forming a partof this specification. Figure 1 is a rear end elevation of a wagon provided with an end gate and lifting jack constructed in accordance with the present invention. Fig. 2 is a horizontal and longitudinal section through the end gate and lifting jack shown in Fig. 1, and taken on the line 22 thereon. Fig. 3 is a side elevation of the end gate and lifting jack in position for use as a lifting jack. Fig. 4 is a perspective view of the supporting plate. Fig. 5 is a similar view of the foot piece which engages the article to be raised. Fig. 6 is a vertical section through the guide member. Fig. 7 is a transverse section through the guide member. Fig. 8 is a section on the line S8 of Fig. 2.

Like reference numerals indicate corresponding parts in the different figures of the drawing.

The end gate and lifting jack of the present invention is made up of a base 1 and a lever 2, said members being hinged together, as indicated at 3, the hinge thereof being provided with leaves 4 which extend transversely a distance about equal to the width of the members 1 and 2 as indicated by the dotted lines in Fig. 1. The base 1 on the same side thereof as the hinge 3 is provided with a transversely extending cleat 5, and

the lever 2 on the'same side thereof is rovided with a similar transversely extcn ing cleat 7. Secured to the base 1 on the side thereof opposite the cleat 5 is a frame 8 which preferably is constructed of metal bent into the shape illustrated in Fig. 1, the free ends of the metal at the upper end of the frame 8 being bent into parallelism with each other as indicated at 9. The means for securing the frame 8 to the base 1 preferably consists of the bolts 10, 11 and 12. The bolt 10 as shown clearly in Fig. 2 extends through the cleat 5 and at its opposite end is reversely bent to form a hook 13 the end of which projects into a suitable socket in the base 1. The hook formed on the bolt 10 engages the base of the frame 8 and thus secures said frame securely to the base 1 in addition to holding the cleat 5 firmly in place. The bolts 11 and 12 are similarly bent to form hooks to engage the frame 8,and said bolts at their opposite ends as indicated in Fig. 2, engage the leaf 1 of the hinge 3. It will be seen therefore that the bolts 10, 11 and 12 simplify and strengthen the entire construction of the device, as they secure the hinge and the cleat in place and also cause both of said members to brace the base 1 on one side and by holding the frame 8 securely against the opposite side, cause the said frame also to brace the member 1.

Secured to the lever 2 on the side thereof opposite the hinge 3 is a supporting plate 15 having lateral extensions 16 which fit flat against the lever 2 and serve to brace the same. The means for securing the supporting plate 15 in position preferably consists of bolts 17 which extend through the plate 15, lever 2 and leaf 4 of the hinge 3, whercby the screws or bolts 17 serve to secure both the hinge and the supporting plate in posi tion on opposite sides of the lever 2. The supporting plate 15 is formed with a forward extension 18 on which is mounted a fin or web 19 with which is pivotally connected the lifting bar 20, said lifting bar being preferably forked or bifurcated as indicated at 21 so as to straddle the fin 19 the bar 20 being pivotally connected with said fin as indicated at 22. The lifting bar 20 at the free end thereof extends through a guide member or yoke 23 which, as shown in Figs. 6 and 7 is provided with pintles 6 that engage oppositely alined openings in the parallel ends 9 of the frame 8 and serves to guide the lifting bar in its up and down at their lower edges by a web 32 shown in Fig.

2 and at their upper edges by a web 33. The outer edge of the web 33 preferably is sharpened at the lower point thereof as indicated at 3% and the inner edge of the web 32 is similarly sharpened at the lowest point thereof as indicated at 35, the sharpened edges 34: and 35 serving to bite into the for ward and rear edges of the lifting bar 20 when the parts are in a position illustrated in Fig. 3 so as to hold the foot in any position to which it has been adjusted. hen the lifting jack is not in operation and is used as an end gate as shown in Figs. 1 and 2 the frame 8 and the lifting bar 20 are folded along the lever 2. The thickness of l the web 33 of the foot, as shown in Fig. 2,

The means for locking the parts in the position shown in Figs, l and 2 preferably comprise a bolt 40 which extends through the lever 2, and at its inner end within a suitable slotor recess formed in the cleat 7 is provided with oppositely extending portions 41 which serve to produce a T-bolt which is capable of swinging movement so as to be moved into position between the parallel portions 9 of the frame 8. Ahandle nut 43 is screwed upon the bolt 40 for the purpose of locking the end gate in the position shown in Figs. 1 and 2.

That is claimed is:

An end gate and lifting jack comprising a lever, a base, a leaf hinge between the a lifting bar connected with the lever, and a foot adjustable on the lifting bar.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
